A fully-resourced lesson which looks at the gaseous reversible reaction known as the Haber Process and then explores and explains why the specific conditions are chosen for this reaction. The lesson includes a detailed lesson presentation (29 slides) and associated worksheets which are differentiated.
The lesson begins by challenging the students to use a description of the reaction to complete the balanced symbol equation. A quiz competition involving both Chemistry and Maths skills is used to reveal the temperature and pressure which are chosen for this reaction. Students will learn that this only produces a yield of 30% and therefore are encouraged to question why these conditions are chosen. In doing so, they are made to wear two “hats”, so that they consider it from both a Science angle but also a business angle. Their knowledge of reversible reactions and the effect of changing either the temperature or the pressure on the position of the equilibrium are constantly challenged and then checked through a range of progress check questions. As a result of this lesson, students will understand that these conditions are a compromise and be able to explain why.
This lesson has been designed for GCSE students (14 - 16 year olds in the UK).
